Watch: Howard Dean vs. Tony Fratto on Obamacare

This is 'so Washington': Dean

Republican Tony Fratto says problems plaguing Obamacare go far beyond the the botched rollout of its troublesome website. Democrat Howard Dean begs to differ.

The two appeared Monday on CNBC's "Squawk on the Street."

"Some of the bigger problems ... are not with the website," Fratto said. "They're with the programmatic pieces of it, like the expansion of Medicaid and some of the new costs that some of the new enrollees are finding that they're going to have to pay for their plans."

The White House deputy press secretary under George W. Bush added: "The expansion of the Medicaid side of this is surprising a lot of people, and the numbers are far bigger than what was anticipated."

Dean, the former Vermont governor, disagreed.

"I don't think there are a lot other problems besides the website. This system that's being used in Obamacare is what Mitt Romney did in Massachusetts and it worked very well. We're five years later and 98.5 percent have their health-care plans.It's extraordinary in this country."
